Serialism is a technique for creating music that uses a set of notes that are used in scrict order. It is also known as twelve-tone music as it uses all 12 notes of a scale and thus has no key. The music makes use of angular “melodies” (that don’t sound like melodies at all) where notes jump from high notes to lower notes and back again. When listening to the music you will notice that there is alot of contrast in dynamics and pitch – to the pont where listening often becomes very uncomfortable. The aim of the composer was to pour lots of emotion into the music and that is why it probably sounds so intense.
